f IMPROVEMENT IN'CRK-CUTTING MACHINES.

Specification forming part of Letters Patent No. 207,772, datedSeptember 3,1878 application tiled i August 15,1878.

To all whom 'it may concern:

Be it jknown that I, JOSEPH PIGASO, of the city, county, and State-ofNewYork, have 'invented a new and useful Improvement in' Cork- OuttingMachines, which improvement is fully set forth in the followingspecification, reference being had to the accompanying drawing, inwhichf Y Figure l is a front view of the machine. Fig. 2 is a rear viewof the same. Fig. 3 is a plan view with some parts broken away. Fig. 4is an inverted-plan view. Fig. 5 is a section in the plane x, Fig. 3.Fig. 6 is an enlarged view of the lever and arm for operating the gage.

Similar letters indicate corresponding parts.

My invention relates to that class of corkcutting machines described inLetters Patent granted to Antonio Fabre, dated vJanuary 8, 1878, No.199,047 and consists in the combination, in a cork-cutting machine, ofan ad-` j ustable gage forregulatin g the size of the corkblank, with abed-plate, a knife -receiving socket in said bed-plate, a knife-guidelocated above the bed-plate, and a blank-cutting knife moving onsaidguide and projecting into the receiving-socket, said knife, in itsbackward movement, causing the gage to move slightly outward, and in itsforward motion allowing the gage to return to its original position,thus leaving' the knife free to pass'through and cut the blank withoutbeing jammed; also, in the combination, with the parts above enumerated,of an adjustable side gage placed at or near the end of theknife-receiving socket, so Athat by adjusting said gage the blank-cutting knife is caused to taper the blaik, a-lso, in the combination, in acork-cuttin g machine, of an adjustable clutch-shaft, a hingednishing-knife, and an adjustable knife-rest, on which saidfinishing-knife reciprocates, so that by adjusting the clutch-shaft andknife-rest with relation to each other the finishing-knife is caused tocut any desired thickness of cork.

In the drawing, the letter A designates the bed-plate of my machine, inwhich is formed a knife receiving socket, b. B is a knife-guide, havingthe form of arod, which is located above the bed-plate A, and supportedby standards a a. C is the blade of the blank-cutting knife, preferablymade with an oblique cutting-edge,

and which is secured to a stock, d, embracing :the guide B, so as tomove or slide thereon, and

having a handle, c.

- Ifit is desired to cut a blank,`the knife C is drawn back by means ofthe handle c to the position shown in Fig. 42. KVThe vknife is'drawnback far enough to allowa stripof cork to be placed on the bed-plate Aover the slot b, so that when the knife passes back to-its originalposition it cuts a blank from the strip of cork. To the stock d of theknife O is fastened a cord or chain, o, which passes over a pulley, p,and is wound around a pulley, q. If the knife is drawn back to theposition shown in Fi 2, the cord or chain ois unwound from thepulley q,and in causing said pulley to revolve, the

small pulley-wheel r, which is keyed to the `same shaft on which thepulley p is keyed, is

alsovcaused to revolve, the cord or chain s is wound upon said wheel r,and the treadle M is raised. By pressing the treadle down the knife Oreturns to its original position, and in sodoing cuts oft' a blank.A Thewidth of the blank cut oftl by the knife C is regulated by a gage, D,which gage can be adjusted by means of the set-screw c, Figs. 3 and 5,which passes through the slot t of the gage D. The other end of theset-screw c is received by the forked end of a bell-crank lever, u c,Fig. 4, the arm c of which is pivoted to a bar or rod, N. This rod N isconnected by means of pivots x with levers or arms w, which turn aboutpivots or lugs, which pivots are fastened to the frame A of the machine.

When the knife O is drawn back to the position shown in Fig. 2, theblade of said knife strikes against the arman of one of the levers w,which arms project into its path, and in so doing causes the inner endof the lever, together with the rod N, to move a small djstance in thedirection of the arrow shown onit in Fig. 4: By this movement of the rodN the gage D is caused to move outward through the action of thebell-crank lever u a. When the knife C moves forward in the act ofcutting a blank, said knife passes away from the arm w', and the springO, Fig. 4, which is fastened at one end to the sliding bar or rod N andat the other to the frame of themachine, causes the rod N to slide backto its original position, whereby the gage D moves slightly in ward. Ofcourse, this spring O could be replaced by a weight or any otherequivalent motor. By causing the gage D to move inward, as described,the knife C can pass through the strip of cork without pressing the edgeof said strip against the gage D while cutting, and thus I prevent theknife C from getting jammed or wedged into the strip of cork, removingall liability of the knife being broken from this cause. Anotheradvantage of this arrangement is that the blanks, as they are cut fromthe strip of cork, are left free to fall through the opening Pin theframe of the machine, thus allowing the knife G to be operatedcontinuously and without any loss of time.

In order to allow the knife C to be drawn back far enough for strips ofcork of varying breadth, it is necessary that the arms w can be removedout of the path of the knife C, thus allowing said knife to pass back tothe required distance. To accomplish this object, the inner ends of thearms w' pass into grooves in the levers w, Fig. 6. In the ends of thearms 'w' are slots c', through which pass pivots b', which pivots arefastened at each end to the levers w. If, now, one of the arms w ispulled outward and as far as the slot a permits, said arm w can beturned down to the position shown in dotted lines in Fig. 6.

If the arm to is raised to a horizontal position and then pushed inwardas far as the slot a. permits, said arm w is held up in a horizoutalposition, and projects into the path of the knife G.

When it is desired to cut the blanks of a tapering form, the side gageQ, Fig. 3, is turned about the pivot c', and is held in position by theset-screw e. The strip of cork is then placed with one edge restingagainst the guide Q, whereby the strip of cork is presen-ted to theknife more or less obliquely, according to the distance the guides Qhave been turned. By this means the blanks can be cut off more or lesstapering.

The letter E, Figs. 1 and 3, designates the two sections of a clutchsecured to the inner ends of a divided shaft, F, which has its bearingsin standards Gr rising from the bed-plate A. Adjacent to theclutch-shaft F is located a guide, H, for the nishing-knife I, whichguide has the form of a rod supported by standards. The blade of thefinishing-knife I is secured to a stock, h, which embraces the guide H,so as to move or slide thereon, and 1s supported by a rest or bracket,J, Fig. 5.

This knife-stock has a handle, t'. The rest or bracket J can be raisedor lowered by means of the adjusting-screw k', Fig. 5, by which meansthe cutting-edge of the knife is caused to pass farther from or nearerto the blank secured in the clutch F, and thus shape the blank into acork of larger or smaller diameter. The clutch F can also be adjusted bymeans of the set-screw s in the standard G, thus further determining thediameter of the cork to be cut. The operation of these parts issubstantially the same as that described in the patent to A. Fabre,wherefore a detailed de scription of them is deemed unnecessary.

I distinctly disclaim everything shown and described in the patent toAntonio Fabre, dated January 8, 1878, No. 199,047.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a cork-cutting machine, of an adjustable gage, D,for regulating the size of the cork-blank, with a bed-plate, aknife-receiving socket in said bedplate, a knifeguide located above thebed-plate, a blank-cutting knife moving on said guide and projectinginto the receiving-socket, and mechanism which is acted on by said knifein its backward movement, causing the gage to move slightly outward,while during the forward motion of the knife the gage is allowed toreturn to its original position, substantially in l the manner and forthe purpose set forth.

2. The combination, in a cork-cutting machine, of an adjustable gage, D,with a bedplate, a knife-receiving socket in said bedplate, aknife-guide located above the bedplate, a blank-cutting knife moving onsaid guide and projecting into the receiving-socket, and an adjustableside gage, Q, placed at or near the end of the knife-rcceiving socket,all combined and adapted to operate substantially as set forth.

3. The combination, in a cork-cutting machine, of an adjustableclutch-shaft, a hinged finishing-knife, and an adjustable knife-rest,

on which said finishing-knife reciprocates,'so that the clutch-shaft andknife-rest can be adjusted with relation to each other, substantially asand for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 8th day of August, 1878.
